Brain Cool AB and University of Edinburgh Announce Phase One Clinical Trial

Brain Cool AB and University of Edinburgh Announce Phase One Clinical Trial to
Test New Medical Brain Cooling Device.

Advanced System Holds Promise as Potentially Life-Saving Early Intervention for
Stroke Patients.
LUND, Sweden and EDINBURGH, Scotland (March 4, 2013)—Brain Cool AB announced
today that its new medical device for therapeutic brain cooling is being tested
in a clinical trial at the University of Edinburgh. Developed initially for use
with stroke patients, Brain Cool has promising implications for use in other
patient groups as well. In this University of Edinburgh clinical trial, the
device is being tested on healthy volunteers to measure efficacy of brain
cooling rates.

Brain Cool uses a patented cooling method developed by Dignitana, a world leader
in scalp-cooling technology and the maker of the DigniCap™ System for the
prevention of chemotherapy-related hair loss. The advanced technology used in
the new Brain Cool System allows cooling of the neck, which helps to speed
perfusion and cooling of blood before it reaches the brain—a critical
intervention for patients suffering from stroke. Brain Cool is the first medical
device now available for clinical use to be tested for this purpose.

Therapeutic hypothermia, or cooling, lowers a patient’s body temperature to help
reduce the risk of injury to the brain following a period of insufficient blood
flow due to an ischemic event such as cardiac arrest, stroke, traumatic brain
injury or neonatal asphyxia. A reduction of body temperature to 35 °C induces a
kind of hibernation status of the brain that may help protect the brain from
stroke-induced damage.

"Every day 1,000 Europeans die from stroke—that’s one every 90 seconds—and about
twice that number survive but are disabled,” said Dr. Malcolm Macleod, Professor
of Neurology and Translational Neuroscience and Head of experimental
neuroscience at the Centre for Clinical Brain Sciences at the University of
Edinburgh.

Stroke is the second largest cause of long-term disability in developed
countries, and the second cause of death worldwide. Even in this advanced
medical age, stroke patients today have little or no access to immediate and
effective therapy, thus, tragically, two thirds of stroke patients remain
disabled or die following a stroke.

“A further advantage,” Dr. Macleod adds, “is that cooling can be used in the
vast majority of stroke patients. This is not the case for clot-bursting drugs,
which can be used only in about one of five patients. The technology from Brain
Cool AB is particularly interesting due to the possibility of using selective
brain cooling only, and that it can be initiated at a very early phase. In time
it might be possible to initiate brain cooling in the back of ambulances.”

Results from previous pilot studies suggest that even a small reduction of the
brain temperature—as little as 1°C, some scientists believe—could be beneficial
in treating stroke patients, and may even contribute to significantly reduced
mortality rates and improved quality of life for stroke survivors.

“The number of patients who could potentially be helped by brain cooling is
substantial,” said Martin Waleij, CEO of Dignitana AB and Chairman of the Board
for Brain Cool AB. “We expect the findings of this clinical trial at the
University of Edinburgh to firmly confirm our pilot evaluations and provide
solid clinical evidence for the use of medical cooling primarily in stroke
patients. In addition to the indication for use in stroke, new patent
applications have also been submitted in the US complementary to the existing
worldwide patents of Dignitana AB.”

Brain Cool’s ease of use provides a significantly more efficient and tolerable
therapeutic cooling method than other devices currently being tested for cooling
the brain. Unlike these other therapies, Brain Cool offers flexibility and ease
of use for both patient and clinician. The body remains completely free and
unrestricted during use, and most patients are awake or resting calmly during
treatment.

An advanced Brain Cool model that can be easily transported is currently in
development in addition to the standard Brain Cool System now available.
Portability and ease of use could make this new medical device particularly
advantageous for stroke patients, for whom immediate intervention can be
critical.

“With nearly 150,000 people suffering a stroke each year in the UK, the patient
need for measures like brain cooling that offer protection of the brain is
obvious,” adds Waleij. “Saved lives and improved quality of life for surviving
patients mean improved health and economic gains for all of society. We are
opening the door to a new world of advanced healing that could improve quality
of life for people with stroke, traumatic brain injury, cardiac arrest, and
neonatal asphyxia.”

About University of Edinburgh Centre for Clinical Brain Sciences

The Centre for Clinical Brain Sciences (CCBS) was established in 2004 and is a
part of University of Edinburgh. It is a multidisciplinary translational "centre
without walls" combining basic and applied research to study the causes,
consequences and treatment of major brain disorders. An explicit aim of the
Centre is to discover and deliver novel therapies for brain disorders.
